Claims.

My invention relates to and has for a purpose the provision of a mechanism to provide a means of depositing about and affixing to the neck of a bottle a revenue seal stamp as provided by law. A further purpose of my invention is to provide a means whereby one and the same mechanism will deposit and aflix about the neck of bottles of several sizes a revenue seal stamp. A further purpose of my invention is to provide a means of depositing about and afiixing ,to the neck of a bottle a revenue seal stamp applicable to conventional conveyor systems. A further purpose of my invention is to provide a means of depositing about and affixing to the neck of a bottle a revenue seal stamp, mechanically rather than manually, as is now common in the art, to theend that such revenue seal stamps be afiixed to the neck of the bottle more rapidly and with greater ease and accuracy.

I have chosen to show my mechanism With a minimum number of appliers, however, an indefinite number of appliers may be used according to the needs of the user.

Briefly, my invention consists of a number of retractable arms pivotably fixed to a central shaft and moving a like number of magazines or containers of revenue seal stamps and a like number of pivotably fixed retractable arms moving a like number of appliers through a cycle whose principal function consists of the removal of the seal stamp from its magazine, the retention of the seal stamp While passing over and in contact with an adhesive applicator, the depositing of the revenue seal stamp centrally across the cap of a bottle perpendicular to the vertical axisof the bottle, the release'of the seal stamp by the applicator, and the compression of the revenue .seal stamp longitudinally along the neck of the bottle. My mechanism operates in a continuous rotary cycle, the point of admission of the bottle being diametrically opposite the point of discharge.

In describing the invention in detail references will be made to the accompanying drawings wherein like characters denote, like and corresponding parts throughout the several views and in which:

Plunger end 61, compression spring 63, longitudinal slot 69 in arm 23, together with pin '54 fixed in plunger end 61, serve to limit the movement of transfer head 28. Arm 3% supports and guides magazine 35 by means of plunger H retained within arm 36 by means of cap [2, and compression spring l3 as shown in Figure '7. 8b is an adhesive reservoir fixed to base I i) at point R. 5! is an adhesive distributing roller journalled to reservoir 85] and driven from auxiliary shaft 48 (drive notshownl 82 is an adhesive volume adjustment adjustably fastened to reservoir Bil by adjusting screw 33.

In operation, revenue seal stamps 52 are inserted within the magazine 35 and are compressed against surface E-E of magazine 35 by the action of floating bottom Eli and compression springs 61-6 A similar procedure is adopted for magazines 35', 35" and 35". My invention is then set in motion by the introduction of an electric current to motor [2 in the conventional manner. Energy is transmitted from the motor I! by means of coupling l2 to speed reduction gearing E35 and thence by means of coupling [3' to main drive shaft 14, Fixed to shaft I4 is driving spur gear I5 which meshes driving spur gear l5 and thus produces rotary motion to shaft 31 to which it is fixed. Gears l5 and 16 being of equal size and pitch produce a uniform motion in shafts i4 and 3'1. Magazines supporting arms 35, 35', 3B" and 35" are pivotably fixed to shaft 3'] by means of coupling 38 and receive a rotary motion from shaft 37. Transfer arms 23., 23, 23" and 23 are pivotably fixed to shaft M by means of flexible coupling 24 and receive a rotary motion from shaft 4. The rotary motions of supporting arms 35, 135", at" and 35" are equal to the rotary motions of transfer arms 23, 23', 23" and 23" and the gears l5 and [6 are so meshed that supporting arm 35 arrives on a common center line simultaneously with transfer arm 23, 35 is on a common center line simultaneously with 23', 35 arrives on a common center line with 23", 35" arrives on a common center line simultaneously with 23", as they each respectively approach position marked S in, Figure 1, thus placing surfaces L, N and M directly over the top P-P of magazine 35. A projection on cam 39 raises arm magazine 35 so that surfaces P-P are in immediate contact with .suction cups 4l-4l-4l of transfer head 28. As arm 3.6 advances through its angular motion, magazine 25 follows cam 44 in a straight line to a predetermined point T. This is accomplished by the advancement of plunger ii in arm 36, As arm 23 advances through its angular motion, transfer fingers 2B follow cams 25 in a straight line to a predetermined point T. During this period of travel, vacuum chambers 42-42-42 and suction rect-ly under point R is adhesive reservoir 80, ad-

hesive distributor roller BI and adhesive volume adjustment 82. Transfer head 28 carrying revenue seal stamp 62 passes over adhesive distributing roller 8| thus applying an adhesive to a surface of revenue seal stamp 52. As transfer arm 23 approaches star wheel 20, a bottle from the conveyor rack (not shown) is. placed by means of star wheel 23 on platform 3lldirectly under transfer head 28. Platform is slidably engaged in bracket arm 29 which in turn is fixed to shaft [4, thus the bottle on platform 30 maintains a constant relationship to transfer head 23. As transfer head 28 and platform 34 continue through the cycle, yoke 53 is depressed by the action of cams 26 and 25 on rollers 52 and 52. This in turn depresses plungers 56 and 56 that move over surfaces D, D of vacuum chambers 42-42 which cause vacuum chambers 42-42 to rotate about pivotal point X-X of intermediate member A with the result that transfer head 28 assumes a position as shown in Figure 6 with the neck of the bottle in the space W and spring 54 is in compression. At this point of the cycle, cams 55, 53' and 55" release vacuum actuating Valve 44, 45, 48 thus releasing seal stamp from transfer finger 28. Transfer head 28 retains the position shown in Figure 6 until it approaches star wheel I 9 where, by reason of the action of rollers 52-52 mounted on yoke 53 and cams 25, 26' and spring 54 which is released and by the assistance of tension springs 58-58, transfer head 28 assumes the position shown in Figure 4. Thus by reason of the adhesive on seal stamp 62, seal stamp 62 remains affixed to the neck of the bottle. Star wheel !9 removes the-bottle from platform 30 and transfers it to the outgoing conveyor (not shown). This cycle of events is repeated with each and successive arms. Where it is desired to adjust my invention to receive bottles of varying heights, internally threaded hand wheel 33 is turned in the required direction on threaded screw 34, thus raising or lowering yoke 32 and variable cam 3|. This varies the height of platforms 30, 30', and 30" relative to the transferheadsZB, 28', 28" and 28". In reducing my invention to practice, certain features of construction, combination and arrangement of parts may necessitate alterations to which the patentee is entitled provided such alterations are comprehended within the scope of what is claimed.

What I claim is: a
